One account key with no scopes, and the MCP's OAuth grants a single mcp.full scope.\n\n## Before you call either\n\n### Postiz API + MCP\n\n1. Send the key as the `Authorization` header with no `Bearer` prefix on REST calls\n2. Batch several posts into one create request to stay under 90 an hour\n3. Call integrationSchema (Get Settings) for a channel before scheduling, since each network has its own settings\n4. Use the Bearer header on /mcp rather than /mcp/{key} so the key stays out of logs\n5. Read output.errors on a failed schedule call and retry with the corrected fields\n\n### Upload-Post API + MCP\n\n1. Send `Authorization: Apikey \u003ckey\u003e` on REST. The MCP also takes Bearer\n2. Use async_upload=true for video, then poll the upload status endpoint every 5 to 60 seconds, not faster\n3. Send an Idempotency-Key on every upload so a timed-out retry doesn't post twice\n4. Check each platform's success flag in results, because one network failing doesn't stop the others\n5.
